The only thing worse than a pseudointellectual is one that thinks they're always right. That's the predicament here with you. Mentioning a person's ethnicity is stormfront-esque? Don't be stupid. Let's ask Google Translate what the origin of Helwani is and let it provide a rough translation of what it means.
The term Semitic is still used and not just when discussing Jews. It's common in the world of linguistics considering that both Hebrew & Arabic are Semitic languages. Since you mentioned genes though perhaps you should know that Arabs & Jews genetically are closely related. They share recent ancestry in common on the paternal side. Same group of people, as I said previously. Oh, and before you say that Mizrahi Jews aren't covered here, they are. Kurdish Jews are Mizrahi. The latter is just a blanket term.
“In a study of Israeli Jews from some different groups (Ashkenazi Jews, Kurdish Jews, North African Sephardi Jews, and Iraqi Jews) and Palestinian Muslim Arabs, more than 70% of the Jewish men and 82% of the Arab men whose DNA was studied had inherited their Y chromosomes from the same paternal ancestors, who lived in the region within the last few thousand years.”
